Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a skin cleaning device for hematopoietic stem cell transplantation care. Background Art

[0002] Hematopoietic stem cell transplantation is an important treatment method, widely used in the treatment of blood system diseases, immune system diseases and certain malignant tumors. After the transplantation operation, the patient's immune system is in an extremely low state and is extremely susceptible to invasion by external pathogenic microorganisms. Therefore, postoperative care is crucial, especially the cleaning and disinfection of the skin at the transplantation site, which is a key link in preventing infection, promoting wound healing and improving the success rate of transplantation.

[0003] Patent announcement number CN217161926U discloses a skin cleanser for the care of hematopoietic stem cell transplantation for blood diseases. Although this patent replaces the method of repeatedly adhering cleaning fluid to a medical sponge to clean the patient's transplanted area, since patients need to perform local cleaning multiple times a day after surgery, medical staff need to repeatedly roll the cleaning roller for cleaning, which can easily cause hand fatigue and affect work efficiency. Secondly, manual wiping makes it difficult to ensure consistent pressure each time, which may lead to incomplete cleaning or irritation of the wound, affecting the quality of wound healing. Thirdly, the operating techniques, strength, and cleaning range of different medical staff may vary, resulting in unstable nursing effects, which is not conducive to the unified management and evaluation of postoperative recovery.

[0036] The lid 301 is first pulled upward to squeeze the rubber ring 302 and deform it, so that the rubber ring 302 leaves the annular groove 303, and then the rubber ring 302 releases the limit of the lid 301. Then the lid 301 is removed from the storage frame 2. When the rubber ring 302 is separated from the lid 301, the rubber ring 302 returns to its original shape. Then, the cotton towel folded like a tissue paper is put into the storage frame 2, and the first piece of cotton towel is inserted into the rectangular hole of the storage frame 2. Then the lid 301 is put back on the storage frame 2, so that the bottom of the pressure plate 305 contacts the folded cotton towel, and then the lid 301 is pressed downward to reset. The first spring 304 is compressed. When the rubber ring 302 contacts the lid 301, the lid is When the rubber ring 302 is aligned with the annular groove 303, the rubber ring 302 is stuck in the annular groove 303, so that the rubber ring 302 limits the cover 301, and the pressure plate 305 is affected by the elastic force of the first spring 304. The first spring 304 applies pressure to make the pressure plate 305 press the folded cotton towels (the pressure will gradually decrease as the cotton towels are used, and the first spring 304 will gradually reset and drive the pressure plate 305 to move downward, so that the pressure plate 305 continues to squeeze the folded cotton towels); then turn and twist the frame cover on the top of the liquid storage frame 1601, pour an appropriate amount of disinfectant into the liquid storage frame 1601, and then reverse and twist the frame cover back onto the liquid storage frame 1601. When in use, the bottom of the shell 1 is placed close to the patient's transplant site, and then the sprocket 701 is driven to rotate by the servo motor 8, so that the sprocket 701 drives the chain 702 to move counterclockwise, thereby driving the connecting frame 9 and the rotating tube 10 to move counterclockwise. When the rotating tube 10 contacts the upper positioning head 1303, the rotating tube 10 will squeeze the upper positioning head 1303 to move forward, and the second spring 1304 is compressed. When the rotating tube 10 is aligned with the upper positioning head 1303, the second spring 1304 returns to its original state, and the second spring 1304 drives the upper positioning head 1303 to move backward and reset, so that the upper positioning head 1303 is docked with the rotating tube 10. Then the sprocket 701 is driven to stop rotating by the servo motor 8, and then the electric When the nail plate 6 contacts the first cotton towel, the nail plate 6 will push the first cotton towel to move to the left. When the first cotton towel contacts the guide plate 4, the guide plate 4 will block the movement of the first cotton towel. When the nail plate 6 continues to move to the lower left, the nail plate 6 will be nailed into the first cotton towel, and the nail plate 6 will drive the first cotton towel to move to the lower left, so that the first cotton towel leaves the storage frame 2, and the first cotton towel drives the next cotton towel to extend out of the storage frame 2. At the same time, when the nail plate 6 drives the cotton towel to move to the lower left, the nail plate 6 will drive the cotton towel to squeeze the guide plate 4 and deform, so that the guide plate 4 does not block The cotton towel is moved until the end of the cotton towel falls between the nearest air bag 12 and the connecting plate 1101, and then the corresponding air pump 1301 is used to draw air into the air bag 12 through the first air pipe 1302, the positioning head 1303, the rotating tube 10 and the connecting tube 1102, so that the corresponding air bag 12 is expanded, so that the corresponding air bag 12 presses the end of the cotton towel against the connecting plate 1101 through expansion, thereby limiting the position of the cotton towel, and then controlling the corresponding electric control valve 1305 to close, so that the corresponding air bag 12 remains in an expanded state, and at the same time stops drawing air into the air bag 12 through the corresponding air pump 1301, and then controlling the telescopic rod of the electric push rod 502 to shorten. Restricted by the rotating plate 503, the electric push rod 502 The telescopic rod will drive the nail plate 6 to move to the upper right and reset, so that the nail plate 6 is separated from the cotton towel. After the nail plate 6 is separated from the cotton towel, the guide plate 4 will return to its original state, and then continue to drive the sprocket 701 to rotate through the servo motor 8, so that the sprocket 701 drives the chain 702 to move counterclockwise, thereby driving the connecting frame 9 and the rotating tube 10 to move counterclockwise, so that the rotating tube 10 squeezes the upper positioning head 1303 to move forward, so that the rotating tube 10 is disconnected from the upper positioning head 1303, and the second spring 1304 is compressed. When the rotating tube 10 is separated from the upper positioning head 1303, the second spring 1304 returns to its original state, and the second spring 1304 drives the upper positioning head 1303 to move backward and reset, and then repeat the above operation.The other airbag 12 is expanded to press the end of the next cotton towel against the other connecting plate 1101, and then the sprocket 701 is driven to rotate by the servo motor 8, so that the sprocket 701 drives the chain 702 to move counterclockwise, thereby driving the connecting frame 9 and the rotating tube 10 to move counterclockwise. When the gear 14 on the rotating tube 10 is engaged with the rack 15, the rack 15 drives the gear 14 to rotate, thereby driving the rotating tube 10, the connecting plate 1101, the connecting tube 1102 and the airbag 12 to rotate, and then driving the cotton towel to be wound, so that the cotton towel is wound into a ball. When the gear 14 on the rotating tube 10 is separated from the rack 15, the gear 14, the rotating tube 10, the connecting plate 1101, the connecting tube 1102 and the airbag 12 are 102 and the airbag 12 stop rotating. When the rotating tube 10 drives the rolled-up cotton towel to move to the bottom of the nozzle 1603, if the cotton towel is the first one, the disinfectant in the liquid storage frame 1601 is pumped into the nozzle 1603 through the water pump 1602, so that the nozzle 1603 sprays the disinfectant on the first cotton towel, and then the disinfectant adheres to the first cotton towel until the first cotton towel is sprayed. If the cotton towel is the second one, there is no need to spray the disinfectant on the second cotton towel. Afterwards, when the rotating tube 10 drives the first rolled-up cotton towel to move to contact the patient's transplant site, the first rolled-up cotton towel will wipe and clean the patient's transplant site. When the patient's transplant site is wiped and cleaned with the cotton towel, the servo motor 8 can also be used to drive the sprocket 701 to perform intermittent forward and reverse movements, so that the sprocket 701 drives the chain 702 to perform intermittent forward and reverse movements, thereby driving the connecting frame 9 and the rotating tube 10 to perform intermittent forward and reverse movements, so that the rotating tube 10 drives the first cotton towel rolled into a ball to move back and forth on the patient's transplant site, thereby wiping the patient's transplant site back and forth. After the patient's transplant site is wiped, the servo motor 8 is continued to drive the sprocket 701 to rotate, so that the sprocket 701 drives the chain 702 to move counterclockwise, thereby driving the connecting frame 9 and the rotating tube 10 to move counterclockwise. When the rotating tube 10 drives the second cotton towel rolled into a ball thereon to move When it comes into contact with the patient's transplant site, the second cotton towel rolled into a ball will wipe the residual disinfectant on the patient's transplant site to prevent the residual disinfectant from causing discomfort to the patient's transplant site. Then, when the rotating tube 10 comes into contact with the lower positioning head 1303, the rotating tube 10 will squeeze the lower positioning head 1303 to move forward, and the second spring 1304 will be compressed. When the rotating tube 10 is aligned with the lower positioning head 1303, the second spring 1304 will return to its original state, and the second spring 1304 will drive the lower positioning head 1303 to move backward and reset, so that the lower positioning head 1303 is docked with the rotating tube 10. Then, the servo motor 8 drives the sprocket 701 to stop rotating, and then controls the corresponding electric control valve 1305 to open.At the same time, the air in the airbag 12 is extracted through the first air pipe 1302, the positioning head 1303, the rotating tube 10 and the connecting tube 1102 by the corresponding air pump 1301, so that the corresponding airbag 12 shrinks and resets, so that the corresponding airbag 12 loosens the end of the cotton towel by shrinking, and then releases the limit of the cotton towel. Then, the brushless motor 1702 drives the lever 1703 to rotate, so that the lever 1703 is located at the front side of the rolled cotton towel, and then the electric slide rail 170 1 drives the brushless motor 1702 and the lever 1703 to move backward, so that the lever 1703 pushes the rolled-up cotton towel to move backward, so that the rolled-up cotton towel passes through the square hole and enters the collection frame 1704, and then the rolled-up cotton towel is separated from the corresponding airbag 12 and the connecting plate 1101. Then, the electric slide rail 1701 drives the brushless motor 1702 and the lever 1703 to move forward and reset, and then the brushless motor 1702 drives the lever 1703 to reverse and reset. Then, the sprocket 701 is driven to rotate by the servo motor 8, so that the sprocket 701 drives the chain 702 to move counterclockwise, thereby driving the connecting frame 9 and the rotating tube 10 to move counterclockwise, so that the rotating tube 10 squeezes the positioning head 1303 on the lower side to move forward, so that the rotating tube 10 is disconnected from the positioning head 1303 on the lower side, and the second spring 1304 is compressed. When the rotating tube 10 is separated from the positioning head 1303 on the lower side, the second spring 1304 returns to its original state, and the second spring 130 4 drives the lower positioning head 1303 to move backward and reset, then repeat the above operation to separate the other rolled cotton towel from the corresponding air bag 12 and connecting plate 1101. In this way, the cotton towels that have been wiped can be automatically collected in the collection frame 1704. Then, the shell 1 is removed from the patient's transplant site, and the baffle 1705 is pulled to the right to make the cotton towels that have been wiped fall down from the collection frame 1704. Then, the baffle 1705 is pushed to the left to reset.

[0037] See Figure 10-12 As shown, it also includes a limiting mechanism, which includes a gear rod 18, a third spring 19 and a guide rail 20; a gear rod 18 is slidably provided on the connecting frame 9, and the gear rod 18 is engaged with the gear 14; a third spring 19 is connected between the gear rod 18 and the connecting frame 9, and a guide rail 20 is connected to the front side of the housing 1, and the gear rod 18 slides on the guide rail 20, and a recessed section is provided on the upper side of the guide rail 20.

[0038] In the initial state, since the guide rail 20 presses against the gear rod 18, the gear rod 18 is engaged with the gear 14, and the third spring 19 is in a stretched state; By setting a limiting mechanism, the gear rod 18 can be used to limit the gear 14 and the rotating tube 10, thereby preventing the rotating tube 10 from rotating arbitrarily and causing the position of the connecting plate 1101, the connecting tube 1102 and the air bag 12 to change, so as to prevent the end of the cotton soft towel from failing to accurately fall between the closest air bag 12 and the connecting plate 1101; when the connecting frame 9 and the rotating tube 10 move counterclockwise, the connecting frame 9 will drive the gear rod 18 to move on the guide rail 20, and when the gear rod 18 moves to the concave section on the guide rail 20, the third spring will be engaged. The spring 19 returns to its original state, and the third spring 19 drives the gear rod 18 to move to the side away from the gear 14, thereby separating the gear rod 18 from the gear 14, and then releasing the limit on the gear 14 and the rotating tube 10, so that the gear 14 rotates after meshing with the rack 15. When the gear rod 18 moves to leave the recessed section on the guide rail 20, the guide rail 20 squeezes the gear rod 18 to move to the side close to the gear 14 and resets it. The third spring 19 stretches, causing the gear rod 18 to mesh with the gear 14, thereby limiting the gear 14 and the rotating tube 10.

[0039] See Figure 10 and Figure 13 As shown, it also includes an adsorption mechanism, which includes a suction cup 21 and a second air pipe 22; the suction cup 21 is installed at intervals on the upper right side of the guide plate 4; the suction cup 21 is connected to the air inlet of the lower air pump 1301 through the second air pipe 22.

[0040] By setting up an adsorption mechanism, before controlling the telescopic rod of the electric push rod 502 to shorten, the air in the suction cup 21 is first extracted through the second air pipe 22 through the lower air pump 1301, so that the next cotton towel is adsorbed on the suction cup 21, and then the telescopic rod of the electric push rod 502 is controlled to shorten. In this way, when the nail plate 6 moves to the upper right and resets, the nail plate 6 is prevented from moving the next cotton towel to the upper right, thereby avoiding the situation where the next cotton towel is to the right of the nail plate 6. After the nail plate 6 moves to the upper right and resets, the lower air pump 1301 is stopped to extract the air in the suction cup 21.
